Flying Diamonds of California
NPJ Single Fin
Flying Diamonds of California “NPJ Single Fin” template fin.
I have spent a lot of time on mid-length single-fin performance boards and have worked on several fin designs to optimize how they work. In the end, I refined the sizes down to just two: 7.5” and 8.0”. For 6’6” - 7’6” with pulled-in tails, go with the 7.5” fin. For larger, wider boards in the 6’8” – 8.0” range, then go with the 8.0” fin. They are upright with a lot of base and lend themselves to no-frills power surfing.
